DeltaTestLocation.row_count() was sufficient for basic validation, but tests that need to inspect table contents or verify file-level behavior require richer access. Add two methods: * read_table(missing_ok=False) → pyarrow.Table | None Returns the current snapshot as a pyarrow Table. Useful for row-level assertions. * log_files(missing_ok=False) → list[str] Returns the list of parquet file URIs in the current snapshot. Useful for verifying compaction, file count, and storage layout. Both follow the existing pattern: deferred deltalake import to avoid aarch64 import crashes, and missing_ok flag to probe caches.
